Piggsy is a deranged and cannibalistic mass murderer, who wears a skinned pig's head over his head while viciously slaughtering victims with a chainsaw. Appearing to be an obese, naked, middle-aged man, he is almost completely inhuman in behavior and has lost all connection with reality. His mind has degraded into an animalistic or child-like state, as he seems to only be capable of speaking a few basic words and grunting/squealing like a pig. His dialogue also strongly implies he is mentally challenged. He is still smart enough, however, to use a chainsaw (his trademark weapon), run away from certain weapons aimed towards him, and to realize that stepping on a metal grate on the floor could be dangerous given his weight, though he ultimately makes the mistake of stepping on it again. He's a remorseless killer, butchering all those who come across his path with his chainsaw.
